The two unreactive gases in the air are nitrogen (about 78%) and oxygen (about 21%).
Neon!
Noble gases are very unreactive.
The element is 'argon' and belongs to noble gas family.
Gold and platinum are two unreactive metals that are found in their native state, meaning they are found in nature in their pure form without the need for further processing.
Argon.
the basically unreactive gas argon (element) is in a light bulb to prevent the tungsten (element) filament from coming into contact with oxygen (element) and getting oxygenated.
helium
Argon is the most unreactive in this series. Cheese is not an element; it is a mixture of compounds.
The two unreactive gases in the air are nitrogen (about 78%) and oxygen (about 21%).
Krypton is an unreactive gas.
Air is mostly Nitrogen.
N2, nitrogen is about 78% in air but does not take part in several reactions as oxygen does so we can say that after noble gases Nitrogen is the least reactive gas or element.
Balls
Inert.
Because helium is an unreactive chemical element.
Neon (Ne) is a noble gas, very unreactive.
